EXPRESS AT-1 will broadcast television signals and data networking services across Eastern Europe and Russia from an operating post at 56 degrees east longitude. Fitted with 32 Ku-band transponders, Express AT1 has a launch mass of approximately 1,800 kilograms, or about 4,000 pounds. It replaces capacity currently offered at the 56 degrees east position by the DirecTV 1R and Bonum 1 satellites, which are at the end of their design lives. RSCC plans to keep DirecTV 1R as a backup to Express AT1, while Bonum 1 is scheduled to be retired from service.
